Software-development tool for presenting telemetry data with associated source code

ABSTRACT

A software-development tool can present telemetry data with associated source code. For example, a computing device can identify, by a text editor, source code of a software application that is associated with telemetry data of performance metrics associated with running the source code. The computing device can display, by the text editor, an icon with the source code. The icon can indicate the source code is associated with the telemetry data. The computing device can receive an interaction with the icon. In response to receiving the interaction, the computing device can retrieve, by the text editor, the telemetry data from a telemetry-data repository for display in the text editor.

TECHNICAL FIELD

The present disclosure relates generally to software development. More specifically, but not by way of limitation, this disclosure relates to a software-development tool for presenting telemetry data with associated source code.

BACKGROUND

Some software-development processes can involve a software developer instrumenting source code for a software application. The instrumentation can be used to generate telemetry data while the software application runs in production. Telemetry data can include logs, metrics, traces, and other performance measurements for the software application. The software developer may decide to access the telemetry data if the software application is performing suboptimally.

DETAILED DESCRIPTION

Telemetry data, such as logs, metrics, and trace information for source code of a software application can be generated by running the software application in production. A software developer may receive a report about the software application. The report may indicate undesirable behavior of the software application. The software developer can then attempt to identify a cause for the undesirable behavior by analyzing the telemetry data. To locate the telemetry data, the software developer may access multiple telemetry tools. Each of the tools may be associated with a particular type of telemetry data. For example, the software developer may access separate telemetry tools for log information, metric counters, and traces for the software application. Once the software developer identifies telemetry data that might explain the undesirable behavior, the software developer can return to the source code to attempt to identify which portion of the source code is causing the undesirable behavior. But, the software developer may not be able to tell which portion of the source code is associated with the identified telemetry data, so the process of editing the source code to mitigate the undesirable behavior may be computationally intensive and time intensive. Additionally, navigating between the various telemetry tools to locate the relevant telemetry data can also contribute to the computational and time requirements for improving source code.

Some examples of the present disclosure can overcome one or more of the abovementioned problems by providing a software-development tool configured to present telemetry data with associated source code. The software-development tool can include a text editor. The text editor can identify source code of a software application that is associated with telemetry data. The text editor may identify an instrumentation point or a predefined annotation that indicates the source code is associated with the telemetry data. The text editor can display an icon with the source code that can indicate that the source code is associated with the telemetry data. The text editor can receive an interaction with the icon and, in response, the text editor can retrieve the telemetry data from a telemetry-data repository for display in the text editor. As a result, the telemetry data can be displayed with the relevant source code, reducing the time and resources involved in locating telemetry data and corresponding source code.

As a more specific example, a user can draft a source code for a software application on a user device using a text editor. The source code can describe a checkout operation for the software application. To aid the user in developing the source code, the user may have downloaded and installed a software-development tool that is a plugin for the text editor. A plugin can be a software component that adds a specific feature or functionality to an existing computer program. As the user drafts the source code in the text editor, the software-development tool plugin can automatically search the software description and determine that the source code includes an instrumentation point for the checkout operation. Based on the instrumentation point, the software-development tool plugin can display an icon that the user can interact with to visualize telemetry data for the checkout operation. Upon the user clicking or hovering over the icon, the software-development tool plugin can retrieve the telemetry data, which can include latency metrics for the checkout operation. The software-development tool plugin displays the latency metrics to the user, who can then determine whether the source code is to be updated to improve latency of the checkout operation. The real-time indication of the telemetry data can reduce the system computation and time for locating and updating source code that may be associated with undesirable performance metrics.

These illustrative examples are given to introduce the reader to the general subject matter discussed here and are not intended to limit the scope of the disclosed concepts. The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements but, like the illustrative examples, should not be used to limit the present disclosure.

FIG. 1 is a block diagram of an example of a system 100 for implementing a software-development tool for presenting telemetry data with associated source code according to some aspects of the present disclosure. The system 100 can include a user device 110. Examples of the user device 110 can include a laptop computer, desktop computer, server, mobile phone, etc. The system 100 can additionally include a server 150 and a telemetry-data repository 140. As shown in FIG. 1 , some or all of these components can communicate with one another via a network 160, such as a local area network (LAN) or the Internet.

In some examples, the user device 110 can include a software-development tool, which may be part of a text editor 120, which can be part of a website, a standalone application, a word processor, an integrated development environment (IDE), etc. A user 102 can interact with the user device 110 to draft source code 130 for a software application in the text editor 120. The source code 130 can be one or more lines of code in any suitable programming language, such as Java or Go. The user 102 may type the source code 130, or may import the source code 130 from another location.

The text editor 120 can identify the source code 130 is associated with telemetry data 144 a. The telemetry data 144 a can be performance metrics associated with running the source code 130. For example, the telemetry data 144 a can be historical log statements, metric counters, or tracing information associated with the source code 130. Further, the telemetry data 144 a can include latency measurements, line graphs for metrics, or flame graphs for traces. The telemetry data 144 a may be generated from running the source code 130 in production, or from running similar source code in production. In some examples, the text editor 120 can identify each portion of the source code 130 that is associated with telemetry data. For example, the text editor may identify multiple lines of the source code 130 that are each associated with different telemetry data. To identify the source code 130 that is associated with the telemetry data 144 a, the text editor 120 can determine the source code 130 includes an indicator, such as an instrumentation point 132 or a predefined annotation 134. The instrumentation point 132 can be a portion of the source code 130 that specifies what is being measured and a name of an operation associated with the measurement. The text editor 120 may identify the instrumentation point 132 based on byte code associated with the source code 130. As an example, the text editor 120 may look for a specific key in a configuration file of the software application to determine a service name (e.g., “order”). The text editor 120 can then determine that the telemetry-data repository 140 includes a corresponding operation (e.g., “POST checkout”) that matches the value of the key.

In some examples, the source code 130 includes the predefined annotation 134 rather than the instrumentation point 132. The predefined annotation 134 can be considered a hint to the text editor 120 that telemetry data exists for the associated source code. The predefined annotation 134 may be a specific character, or string of characters, in the source code 130. For example, the predefined annotation 134 in Go code may be “//+telemetry”. The text editor 120 can then identify the text subsequent to the predefined annotation 134 to determine how to locate the telemetry data 144 a that is associated with the source code 130. For example, the source code 130 may be “//+telemetry:service-name=order,operation=checkout”, so the text editor 120 can determine the telemetry data 144 a is related to the service “order” and the operation “checkout”.

In some examples, subsequent to identifying that the source code 130 is associated with the telemetry data 144 a, the text editor 120 can display an icon 136 with the source code 130. The icon 136 can indicate that the source code 130 is associated with the telemetry data 144 a. The text editor 120 can display the icon at the line of code that is associated with the telemetry data 144 a, such as at the line of the source code 130 that includes the instrumentation point 132 or the predefined annotation 134. The user 102 can then interact with the icon 136, such as by hovering over or clicking the icon 136 with a mouse.

In response to receiving an interaction with the icon 136, the text editor 120 can retrieve the telemetry data 144 a from the telemetry-data repository 140. To retrieve the telemetry data 144 a, the text editor 120 can determine a key-value pair 142 a associated with the telemetry data 144 a based on the source code 130. For example, the key of the key-value pair 142 a can be the “service.name”, or similar, and the value of the key-value pair 142 a can be “order”. In other examples, the key of the key-value pair 142 a can be “operation.name” and the value of the key-value pair 142 a can be “checkout”. The text editor 120 can then query the telemetry-data repository 140 for the key-value pair 142 a to locate the key-value pair 142. The text editor 120 can retrieve the telemetry data 144 a associated with the key-value pair 142 a.

Once the text editor 120 retrieves the telemetry data 144 a from the telemetry-data repository 140, the text editor 120 can display the telemetry data 144 a in the text editor 120. For example, the text editor 120 can display traces, log statements, or metric counters. In some examples, the text editor 120 may display the telemetry data 144 a in a flame graph. The user 102 may use the telemetry data 144 a to determine whether the source code 130 may be prone to errors. If the user 102 determines that the source code 130 is prone to errors, which may be based on the telemetry data 144 a being outside of a desirable range, the user 102 can update the source code 130.

Upon receiving an update to the source code 130, the text editor 120 can determine the source code 130 is associated with telemetry data 144 b. The text editor 120 may identify a key-value pair 142 b from the instrumentation point 132 or the predefined annotation 134 to determine that the source code 130 is associated with the telemetry data 144 b. The text editor 120 can then display the icon 136 with the source code 130. The user 102 can interact with the icon 136 and the text editor 120 can retrieve the telemetry data 144 b from the telemetry-data repository 140. The text editor 120 can then display the telemetry data 144 b in the text editor 120. In some examples, the telemetry data 144 b may be available immediately once the source code 130 is updated, such as if similar source code has been run in production and telemetry data has been generated previously. If similar source code has not run in production, the telemetry data 144 b may be generated and the text editor 120 can display the icon 136 subsequent to the source code 130 being run in production.

The source code 130 may be an endpoint that is called by multiple services. By accessing the telemetry-data repository 140, the text editor 120 can indicate upstream services that are calling the source code 130 and downstream services that are being called by the source code 130. For example, the text editor 120 can determine the telemetry data 144 a is associated with a first service 122 calling the source code 130 and the telemetry data 144 b is associated with a second service 124 calling the source code 130. As an example, the first service 122 is a first tenant of the software application and the second service 124 is a second tenant of the software application. The text editor 120 can determine the telemetry data 144 a-b for calls to a checkout service when called by the first tenant and the second tenant, respectively. The text editor 120 can then display the telemetry data 144 a-b in the text editor 120. Additionally or alternatively, the text editor 120 can display a comparison 138 of the telemetry data 144 a and the telemetry data 144 b. The user 102 may use the comparison 138 to determine which service is associated with more desirable telemetry data and may be able to update the source code 130 so that the service associated with the less desirable telemetry data can be improved.

While FIG. 1 shows a specific number and arrangement of components, other examples may involve more components, fewer components, different components, or a different arrangement of the components shown in FIG. 1 . Additionally, while the above examples attribute certain functionality to the user device 110, other implementations are possible. For example, at least some of the components and functionality can be offloaded to a server 150. As one particular example, the text editor 120 can be part of a webpage generated by the server 150 and served to the user device 110 over the network 160.

FIG. 2 is a diagram of a graphical user interface for a software-development tool presenting telemetry data according to some aspects of the present disclosure. A user, such as a software developer, can navigate to the text editor 220. In some examples, the text editor 220 can include a text box 226 where the user can input source code 230 for a software application. The user can input an instrumentation point 232 as part of the source code 230. The instrumentation point 232 can indicate that there is telemetry data 244 associated with the source code 230.

The text editor 220 can be configured to assist the user in drafting the software application by automatically notifying the user about the telemetry data 244. For example, the text editor 220 can identify the instrumentation point 232 and present an icon 236 indicating there is telemetry data for the source code 230. The user can hover over the icon 136 and the text editor 120 can display the telemetry data 244 to the user. As illustrated in FIG. 2 , the telemetry data 244 includes a median latency of 42 ms and a tail latency of 167 ms. The user can use the telemetry data 244 to determine whether to update the source code 230.

While FIG. 2 shows an example of a text editor 220 for illustrative purposes, other examples may involve more components, fewer components, different components, or a different arrangement of the components shown in FIG. 2 . For example, although the telemetry data 244 is depicted as a popup window in FIG. 2 , in other examples their content can be conveyed to the user using other approaches, such as through a graphical indicator embedded in the text editor 220.

FIG. 3 is a block diagram of another example of a system 300 for implementing a software-development tool for presenting telemetry data with associated source code according to some aspects of the present disclosure. The system 300 includes a processor 302 communicatively coupled with a memory 304. In some examples, the processor 302 and the memory 304 can be part of the same computing device, such as the user device 110 of FIG. 1 . In other examples, the processor 302 and the memory 304 can be distributed from (e.g., remote to) one another.

The processor 302 can include one processor or multiple processors. Non-limiting examples of the processor 302 include a Field-Programmable Gate Array (FPGA), an application-specific integrated circuit (ASIC), a microprocessor, etc. The processor 302 can execute instructions 306 stored in the memory 304 to perform operations. In some examples, the instructions 306 can include processor-specific instructions generated by a compiler or an interpreter from code written in any suitable computer-programming language, such as C, C++, C#, etc.

The memory 304 can include one memory or multiple memories. The memory 304 can be non-volatile and may include any type of memory that retains stored information when powered off. Non-limiting examples of the memory 304 include electrically erasable and programmable read-only memory (EEPROM), flash memory, or any other type of non-volatile memory. At least some of the memory 304 can include a non-transitory computer-readable medium from which the processor 302 can read instructions 306. A computer-readable medium can include electronic, optical, magnetic, or other storage devices capable of providing the processor 302 with computer-readable instructions or other program code. Non-limiting examples of a computer-readable medium include magnetic disk(s), memory chip(s), ROM, random-access memory (RAM), an ASIC, a configured processor, optical storage, or any other medium from which a computer processor can read the instructions 306.

In some examples, the processor 302 can execute instructions 306 to perform various operations. For example, the processor 302 can identify, by a text editor 308, source code 310 of a software application 312 that is associated with telemetry data 314. The telemetry data 314 can be performance metrics 322 associated with running the source code 310. The processor 302 may identify an instrumentation point or a predefined annotation in the source code 310 to determine that the source code 310 is associated with the telemetry data 314. The processor 302 can display, by the text editor 308, an icon 316 with the source code 310. The icon 316 can indicate that the source code 310 is associated with the telemetry data 314. The processor 302 can receive an interaction 318 with the icon 316. The interaction 318 may be a hover over or a click on the icon by a user. In response to receiving the interaction 318, the processor 302 can retrieve, by the text editor 308, the telemetry data 314 from a telemetry-data repository 320 for display in the text editor 308. The processor 302 may determine a key-value pair associated with the telemetry data 314 based on the source code 310, and the processor 302 can locate the key-value pair in the telemetry-data repository 320. By presenting the telemetry data 314 in the text editor 308, the user may not need to access multiple telemetry tools to determine the telemetry data 314 associated with the software application 312. As a result, computing resources and time involved with retrieving the telemetry data 314 and improving the source code 310 to have better performance metrics can be reduced.

FIG. 4 is a flow chart of an example of a process for implementing a software-development tool for presenting telemetry data with associated source code according to some aspects of the present disclosure. In some examples, the processor 302 can implement some or all of the steps shown in FIG. 4 . Other examples can include more steps, fewer steps, different steps, or a different order of the steps than is shown in FIG. 4 . The steps of FIG. 4 are discussed below with reference to the components discussed above in relation to FIG. 3 .

In block 402, a processor 302 identifies, by a text editor 308, source code 310 of a software application 312 that is associated with telemetry data 314. The telemetry data 314 can be performance metrics 322 associated with running the source code 310. The source code 310 can include an instrumentation point or a predefined annotation that indicates the source code 310 is associated with the telemetry data 314. The processor 302 can identify the instrumentation point or the predefined annotation to determine that the source code 310 is associated with the telemetry data 314. The telemetry data 314 can include historical log statements, metric counters, tracing information, or other performance metrics associated with the source code 310.

In block 404, the processor 302 displays, by the text editor 308, an icon 316 with the source code 310. The icon 316 indicates the source code 310 is associated with the telemetry data 314. The processor 302 can display the icon 316 on a line of the source code 310 that includes the instrumentation point or the predefined annotation.

In block 406, the processor 302 receives an interaction 318 with the icon 316. The interaction 318 may be a click, hover, or other interaction on the icon 316 from a user.

In block 408, the processor 302, in response to receiving the interaction 318, retrieves, by the text editor 308, the telemetry data 314 from a telemetry-data repository 320 for display in the text editor 308. The telemetry-data repository 320 can store the telemetry data 314 in a key-value pair. The processor 302 can determine the key-value pair associated with the telemetry data 314 based on the source code 310 and locate the key-value pair in the telemetry-data repository 320. The processor 302 can then retrieve the telemetry data 314 and display the telemetry data 314 in the text editor 308. The telemetry data 314 may be displayed as graphs, such as line graphs or flame graphs, in the text editor 308. The processor 302 may additionally display a comparison between telemetry data associated with a first service calling the source code 310 and telemetry data associated with a second service calling the source code 310. Retrieving and displaying the telemetry data for a software application in a text editor can reduce system computation and time for locating and updating source code that may be associated with undesirable performance metrics.
